the overflow goes through two filter pads and then there is a heater and the return pump. its the same on the white one, just that the overflow is on the left side, instead of the back. the white one is cheaper and doesn't come with a heater though. its called Itank 5g

thanks @Autumnsky! it wont let me quote you, it keeps closing the app on me. thats what I'm thinking of doing I've got a nice piece of dw for the white one and it has black sand already, i just need to add some low light plants and moss and i need to order a par38 for the black one. I'm debating on plumbing the sump on the black one into a separate 10 gallon tank, to keep it more stable.

so far its been working out well, I've had the white one for about a week with my betta in it. i seeded that from his old tank. i still need to figure out exactly what I'm going to do with the nano reef, on the espresso one, before i go any further.

Sounds good and they look nice. I always vote for sump, especially on such a small reef tank.

Did a 4g wc on the 20 long, 5g wc on the 37g, accedently added RODI water instead of saltwater to replace in the 20 but then once i noticed i had already added 3g of fresh so i hope nothing to bad happends...
